ABSTRACT:
The present invention relates to a dope dyed sea-island type conjugate multifilament. In the dope dyed sea-island type conjugate multifilament, which comprises easy soluble polymer as a sea component and polyester as an island component, the island component contains a dope dyed component selected from the group consisting of carbon black, pigments and dyestuffs and the temperature range (Tα-Tβ) showing more than 95% of the maximum thermal stress of yarns is from 120° C. to 210° C. The dope dyed sea-island type conjugate multifilament of the present invention has an excellent thermal shrinkage property and excellent wash fastness and light fastness, and the dyeing process thereof can be omitted after producing a woven or knitted fabric because a dope dyed component is contained in the island component (ultra fine yarn). The dope dyed sea-island type conjugate multifilament of the present invention is useful as yarns for warp knit fabrics used in production of women's apparel.
